DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0018] like Figure 1-7As shown, an automatic waterproof plug provided by the present invention includes a plug body 100, a first sealing connection component 200, a second sealing connection component 300 and a control component 400. The first sealing connection component 200 includes a connecting block 210 and an inner sealing cylinder 220. The connecting block 210 is fixedly connected to the plug body 100. The inner sealing cylinder 220 is slidably connected to the connecting block 210 along the connecting direction of the plug body 100 and the connecting block 210. The second sealing connection component 300 includes an outer sealing cylinder 310, a rotating seal 320 and a driving member 330. The outer sealing cylinder 310 rotates and is sealed with the socket M via the rotating seal 320. The driving member 330 is installed on the socket M and connected to the rotating seal 320 to drive the outer sealing cylinder to rotate. The outer sealing cylinder 310 is threadedly connected to the inner sealing cylinder 220 to form a sealed cavity that wraps the connection between the plug body 100 and the socket M. The control component 400 is installed on the plug body 100 and the socket M to control the action of the driving member 330.

[0019] During implementation, in an automated assembly production line, the connecting block 210 can be clamped by a robot or other equipment to drive the plug body 100 to move, and the plug body 100 can be inserted into the socket M. The robot applies pressure to the inner sealing cylinder 220 to squeeze the outer sealing cylinder 310, and the control component 400 controls the driving member 330 to drive the outer sealing cylinder 310 to rotate. The inner sealing cylinder 220 slides into the outer sealing cylinder 310 under the action of pressure to achieve sealing at the connection between the plug body 100 and the socket M. No manual operation is required, and the assembly efficiency is high.

[0020] like Figure 1 As shown in FIG. 1 , the plug body 100 in this embodiment has a plurality of plug connectors uniformly arranged along the circumference of the inner sealing cylinder 220. Figure 3 As shown in , the socket M in this embodiment has a plurality of jacks evenly arranged along the circumference of the outer sealing cylinder 310. When the plug body 100 is connected to the socket M, a plurality of plug connectors are respectively inserted into the plurality of jacks to achieve electrical connection between the two.

[0021] It should be noted that the plug body 100 and the socket M in this embodiment may also adopt other connection forms, such as a three-prong plug.

[0022] In this embodiment, the first sealing connection assembly 200 and the second sealing connection assembly 300 are connected in cooperation to achieve sealing processing of the connection between the plug body 100 and the socket M.

[0023] The first sealing connection assembly 200 in this embodiment includes a connection block 210 and an inner sealing cylinder 220. The connection block 210 is fixedly connected to the plug body 100, and the inner sealing cylinder 220 is slidingly connected to the connection block 210 along the connecting direction of the plug body 100 and the connection block 210; the second sealing connection assembly 300 includes an outer sealing cylinder 310, a rotating seal 320 and a driving member 330. The outer sealing cylinder 310 rotates and is sealed with the socket M via the rotating seal 320. The driving member 330 is installed on the socket M and is connected to the rotating seal 320 to drive the outer sealing cylinder to rotate. The outer sealing cylinder 310 is threadedly connected to the inner sealing cylinder 220 to form a sealed cavity that wraps the connection between the plug body 100 and the socket M.

[0024] like Figure 1 As shown, in one embodiment, the connection block 210 is cylindrical, and a slide groove 211 is formed on the outer wall of the connection block 210, and the protrusion on the inner wall of the inner sealing cylinder 220 is slidably connected to the slide groove 211. The slide groove 211 is long and extends along the length direction of the connection block 210.

[0025] In one embodiment, an outer wall of one end of the inner sealing cylinder 220 forms an outer thread 221 , an inner wall of one end of the outer sealing cylinder 310 forms an inner thread 311 , and an outer diameter of the inner sealing cylinder 220 is smaller than an inner diameter of the outer sealing cylinder 310 .

[0026] It is understandable that an inner thread 311 may be formed on the inner wall of the inner sealing cylinder 220 , and an outer thread 221 may be formed on the outer wall of the outer sealing cylinder 310 , and the outer diameter of the inner sealing cylinder 220 is greater than the inner diameter of the outer sealing cylinder 310 .

[0027] like Fig.12 As shown, in order to form a sealed cavity, that is, to ensure the airtightness between the inner sealing cylinder 220 and the outer sealing cylinder 310, the embodiment also includes a retaining ring 222 fixedly arranged at one end of the inner sealing cylinder 220 away from the outer sealing cylinder 310, the outer diameter of the retaining ring 222 is not less than the outer diameter of the outer sealing cylinder 310, and the end of the outer sealing cylinder 310 close to the inner sealing cylinder 220 is provided with a sealing ring 312 for abutting against the retaining ring 222. When the inner sealing cylinder 220 and the outer sealing cylinder 310 are threadedly connected, the outer sealing cylinder 310 and the retaining ring 222 are opposite to each other and the sealing ring 312 is squeezed.

[0028] During the process of threaded connection between the inner sealing cylinder 220 and the outer sealing cylinder 310 , the outer sealing cylinder 310 needs to be continuously rotated, and at the same time, the inner sealing cylinder 220 needs to slide in a direction close to the outer sealing cylinder 310 .

[0029] In the above process, in order to prevent the robot and other equipment from continuously applying pressure to the inner sealing tube 220 and affecting the difficulty of operation, the present embodiment also includes a pressure block 230 and a clamping spring 240. The pressure block 230 is fixedly connected to the side of the connecting block 210 away from the plug body 100 via the clamping spring 240.

[0030] After the plug body 100 is connected to the socket M, a robot or other equipment applies a preload force to the compression spring 240 through the pressure block 230, after which the robot stops moving. Under the preload force, the inner sealing cylinder 220 continues to slide in a direction close to the outer sealing cylinder 310 to achieve a threaded connection between the two.

[0031] In this embodiment, the rotating seal 320 includes a gear ring 321, a gear 322 and a thrust bearing 323. The outer sealing cylinder 310 is connected to the socket M via the thrust bearing 323. The connection part of the socket M is located in the outer sealing cylinder 310. The gear ring 321 is sleeved on the outer sealing cylinder 310. The gear 322 is connected to the output end of the driving member 330. The gear 322 is meshed with the gear ring 321.

[0032] The control component 400 in this embodiment is a structure for controlling the action of the driving member 330 .

[0033] like Figure 7-10 As shown, in one embodiment, the control component 400 includes a first electrode sheet 410, a second electrode sheet 420, a power-off spring 430 and a telescopic rod 440. The first electrode sheet 410 is fixedly disposed in the socket M, the second electrode sheet slides in a direction approaching or away from the first electrode sheet 410, and is connected to the socket M via the power-off spring 430, and the telescopic rod 440 is fixedly disposed on the plug body 100, and the telescopic rod 440 moves in a direction pointing to the second electrode sheet 420.

[0034] The device further includes a track 450, a slider and a wire 460. The track 450 is fixedly arranged in the socket M. The first electrode sheet 410 is fixedly connected to the track 450. The slider is slidably connected to the guide rail. One end of the power-off spring 430 is connected to the guide rail, and the other end of the power-off spring 430 is connected to the slider. The second electrode sheet 420 is arranged on a side of the slider close to the first electrode sheet 410. The second electrode sheet 420 is connected to the driving member 330 via the wire 460. The driving member 330 is a motor, and the telescopic rod 440 is a pneumatic rod.

[0035] The control component 400 is built into the installation cavity inside the socket M, and a through hole connected to the installation cavity is opened on one side of the socket M close to the telescopic rod 440.

[0036] When the plug body 100 is connected to the socket M, the pneumatic rod is inflated, and the pneumatic rod extends through the through hole on the socket M and extends to the installation cavity inside the socket M, pushing the slider to slide along the track 450. During the pushing process, the power-off spring 430 is squeezed. Since the air pressure force is greater than the spring elastic force, the spring is compressed, and the slider moves in the track 450. The second electrode sheet 420 on the slider continues to approach the first electrode sheet 410. As the compression is completed, the first electrode sheet 410 and the second electrode sheet 420 contact each other, the slider is energized, and the electricity is transmitted to the motor.

[0037] Compared with the existing technology: Figure 6 and Fig.11 As shown, in the automated assembly production line, the connection block 210 can be clamped by a robot or other equipment to drive the plug body 100 to move, and the plug body 100 can be inserted into the socket M. The robot applies pressure to the inner sealing cylinder 220 to squeeze the outer sealing cylinder 310, and the control component 400 controls the driving member 330 to drive the outer sealing cylinder 310 to rotate. The inner sealing cylinder 220 slides into the outer sealing cylinder 310 under the action of pressure to achieve the sealing of the connection between the plug body 100 and the socket M. No manual operation is required, and the assembly efficiency is high.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
